Lily threw a ball. The balls equation that demonstrated its height and velocity is:

SIZIF [17.4K]

The initial height of the ball is the y-intercept of the function

The initial height she threw the ball from is 35

<h3>How to determine the initial height</h3>

The function is given as:

$h(x) = -16x^2 + 3x +35$

Set x = 0.

So, we have:

$h(0) = -16 * 0^2 + 3*0 +35$

Evaluate the exponent

$h(0) = -16 * 0 + 3 * 0 + 35$

Evaluate the products

$h(0) = 0 + 0 + 35$

Evaluate the sum

$h(0)= 35$

Hence, the initial height she threw the ball from is 35

A TV screen is 41 cm long and 31 cm high. The length of the diagonal is closest to: A) 49 cm Eliminate B) 51 cm C) 54 cm D) 48 c

GuDViN [60]

Answer:

The length of the diagonal is closest to 51 cm.

Step-by-step explanation:

Given:

TV screen is 41 cm long and 31 cm high.

Now, to find the length of the diagonal.

By using pythagorean theorem:

leg 1 = 41 cm, leg 2 = 31 cm.

Let the hypotenuse be $x$ .

(leg 1)² + (leg 2)² = hypotenuse²

$41^{2} +31^{2}=x^{2}$

⇒ $1681+961=x^{2}$

⇒ $2642=x^{2}$

Using square root on both sides we get:

⇒ $51.40=x$

So, the length of the diagonal = 51.40 cm.

By rounding off of 51.40cm it becomes 51 cm.

Therefore, the length of the diagonal is closest to 51 cm.

Awarding road contracts. A state Department of Transportation (DOT) recently claimed that each of five bidders received equal co

Sveta_85 [38]

Answer:

a) Hence, the probability of this event occurring if, in fact, the DOT's claim is true

= 3/10 = 0.3

Step-by-step explanation:

a) The concept applied here is combinatorics ; nCr = n!/(n - r)!r!

we are told that out of 5bidders, Three of the bidders were large construction conglomerates

and two were small specialty contractors.

selecting two recipients with tree of the bidders were large construction conglomerates 3C2

= 3!/(3-2)!2!

= 3

Similarly, selecting the two small casualty contractor from the total of 5bidders = 5C2

= 5!/(5-2)!2!

= 10

Hence, the probability of this event occurring if, in fact, the DOT's claim is true

= 3/10 = 0.3

b) if DOTs claim is not true ( probability of failure) = 1 - 0.3

= 0.7 , this value implies that the probability 0.3 is largely compatible and a compliment of the 0.7 and as such it is consistent with the DOTs claim that the selection was random.
